Protraction Plank Jack
Protraction Plank Jack Exercise Description
The Protraction Plank Jack is a dynamic high-plank variation that combines scapular protraction (“push the floor away”) with rhythmic foot hops in and out. It targets the anterior core and obliques to resist extension and rotation while the lower body moves. Actively protracting the shoulder blades increases shoulder girdle stability and emphasizes the serratus anterior, with the deltoids, triceps, and upper back assisting isometrically. The out–in foot motion raises demands on the glutes and hip abductors/adductors to keep the pelvis level. Expect a steady challenge to trunk stiffness, posture control, and full-body coordination when performed with a neutral spine and controlled landings.

How To Do The Protraction Plank Jack Exercise
‘- Set up in a high plank: hands under shoulders, arms straight, legs long, feet together.
– Spread your fingers and press the floor away to slightly protract the shoulder blades without shrugging.
– Brace the abdominal wall; keep ribs down and maintain a neutral spine from head to heels.
– Lightly squeeze glutes and keep hips level; avoid sagging or piking.
– Shift weight evenly through hands and toes; keep neck neutral with eyes slightly ahead of your hands.
– Hop both feet out to about shoulder-width, landing softly on the balls of the feet.
– Maintain protraction and core brace; do not let the chest sink or the shoulders collapse.
– Hop feet back together under control, minimizing hip sway or trunk rotation.
– Breathe steadily throughout; prioritize quiet, controlled landings and consistent body alignment.
Protraction Plank Jack Tips
‘- Place your hands directly under your shoulders with your arms straight before you start hopping.
– Spread your fingers and actively “push the floor away” to slightly protract your shoulder blades.
– Protract without shrugging; keep your shoulders away from your ears.
– Brace your abdominal wall, keep your ribs down, and maintain a neutral line from head to heels.
– Lightly squeeze your glutes and keep your hips level, avoiding both sagging and piking.
– Distribute weight evenly through your hands and toes and keep your neck neutral with eyes slightly ahead of your hands.
– Hop both feet out to about shoulder-width and land softly on the balls of your feet.
– Keep the shoulder blade protraction and core brace as you move; don’t let your chest sink or your shoulders collapse.
– Hop your feet back together under control, minimizing hip sway and trunk rotation.
– Breathe steadily and aim for quiet, controlled landings with consistent whole-body alignment.
Protraction Plank Jack Beginner Introduction
The Protraction Plank Jack is a lively plank-style core exercise performed from the top of a push-up position with quick foot hops. While the legs jump apart and together in a steady rhythm, the upper body stays strong and still, with the shoulders actively pressing the ground away. This combination turns a simple plank into a full-body challenge that taxes the abs and side abs as they fight unwanted arching or twisting through the midsection.
Because the arms remain straight and the shoulders push firmly, the shoulders, triceps, and upper back work hard to hold a solid frame. At the same time, the glutes, hips, and inner and outer thighs manage the out-and-in motion of the feet, helping the hips stay level. The movement rewards soft, quiet landings and a long, well-organized body line from head to heels, building postural control, stability, and coordination with every rhythm of the feet.
